摘要: Supersonic parachutes are a critical element of planetary mission whose simple structure, light-weight characteristics together with high ratio aerodynamic drag makes them the most suitable decelerators. The use parachute in supersonic flow produces complex shock/shock and wake/shock interaction giving rise to dynamic pressure oscillations. study is difficult, because has very flexible structure which obtaining experimental data difficult. In this study, wind tunnel test using two rigid bodies done. was done at Mach number 3 by varying distance between front rear objects, bundle point divides suspension lines riser. analysis Schlieren movies revealed shock wave oscillation repetitive had large variation. variation differed each case change riser object. causes are: wake caused object wave, fundamental harmonic vibration lines, interference waves, boundary layer lines.
